Refrigeration Install

I'm installing an Adler/Barbour cu100 and in the manual it states to generously lubricate the refrigerant couplings with refrigeration oil. Anybody know what it is and where I can buy it? I've googled it and searched here and have come up empty.

Thanks for any info.

Re: refrigeration install

Enersyn MP S 220 BP Refrigeration Lubricant made by BP. I couldn't find a place to buy small amounts. You could check out Kollman-marine.com. He's the fridge guru. He could help you.

Thanks crazy - I will check the Kollman site. When I search I get results for 5 gallon drums of oil or stuff that sounds like it's for cars. I thought that these Adler/Barbour units were popular with do it yourself installations, so hopefully someone will be able to point me in the right direction with this issue.

Everything else has gone pretty straight forward. Maybe Adler/Barbour expects a refrigeration tech to make the final connections. I have an email out to them as well so hopefully I'll know more soon.

Re: refrigeration install

There is no discernible difference between refrigeration oil for a car AC unit and a 12 volt refrigerator unit. Get it at the local orielies or Napa auto parts.

Make sure you get polyolfatic (SP?) oil used in 134A installations and you will be fine.


Thanks,
Guy

Thank you very much for that info Guy - it's much appreciated. I'll check with the folks at Napa tomorrow - if they have it, I should be able to finish up tomorrow. Thanks again!

Re: refrigeration install

Mineral Oil. Just be VERY careful with how much you use. It's not compatible with many of the refrigerants, but is in tiny fractions. For simple lubrication of a joint, it's not a big deal. Just don't use more than enough to coat the surface. No extra.

Re: refrigeration install

Great unit. I installed my cu-200 just by reading the manual and following the instructions. Ten years later it still works flawlessly.

Re: refrigeration install

As noted, from any auto parts store, just make sure it is the right compatible type for your AC system's gas type. Often it is an "oil charge" of oil with gas in the same can, in which case you'd bleed some out into a cup and then dab it on.

Re: Refrigeration Install

I just thought I'd give a quick update in case someone else is ever looking for this oil. I did go on Kollman's website, and he states that the correct oil is Polyol Ester oil. I was able to find this at my local Autozone - about 12 bucks for a pint.

As it turns out, it may have been unnecessary to track it down. Dometic replied to my email and said that 3 in 1 oil or any light machine oil would work as well.

Thanks to everyone for the help!

Re: Refrigeration Install

Are we allowed to remove our old Alder Barbour? The refrigeration guy hasn't been following up with us, so we will do a last round of trouble shooting this weekend. Unless we find something, we will be ordering both the compressor and the evaporator, as both are looking a bit rough around the edges.
